Steve, sounds to me like an intermittent fault with the ABS sensor, probably the rear one, but could be either as they both provide info to the ECU. Remove the sensors, clean them up if you see any white (aluminum) corrosion in the holders or has transferred onto the sensors. They should not have any path to ground (thus their plastic sleeves). I coat mine with a smidge of silicone or dielectric grease (it won't melt away).
Also, verify the gaps or amount the sensor goes into the adaptor plates. If the sensor is not fully seated (although it may appear to be), excess gap to the trigger wheel may be an issue. I think (just an opinion) they live on the edge of maximum gap by design, but who knows. Clean up and your problem may go away (I could not readily find if there's a spec, there used to be on previous Gens I think, but these are the newer trigger wheel since '08.
A remote possibility is that the wheel trigger plate may have been accidentally bent, the spec. max deflection is 0.0055" or 0.14 mm. Doubt it, but worth a quick check should the condition not go away.
There may be a code set, if so, simply clear it and see if it comes back. Keep us posted.
Keep yer stick on the ice....
